I am looking for a program that can help me to manage my preferred colors. Sometimes I found some nice colors and I would like to be able to save them, to be able to use them later when I need them.
For example I like this green color
#006629 and its lighter version
#00913A. Also I like this orange color
#FF6700 and its lighter version
So I am looking for a color picker (so the user can tweak the colors) that can help me to manage the colors, by making a list with the colors that I want to save, showing them in say 100 x 100 pixel squares and save them to text configuration file. Would be better if it would allow defining separate lists for cold colors, warm colors, bright colors, or whatever other category of colors the user wants to define.
Maybe there are also web apps helping to keep lists of colors and to tweak the colors?
